Albert Porter was 10-years-old the last time he saw his grandpa, John "Alvie" Porter. He now believes he is one of the six bodies recovered from Foss Lake.

Porter said that while it is unusual that both cars ended up in the lake together, he remembers the car his grandpa disappeared in was always having problems and believes it may have been a tragic accident.

"They had to push start that car many, many times to start it," Porter said.

Family members in Sayre, Oklahoma, comment on the cars found at Foss Lake and several of them gave DNA samples to help investigators determine the identities of the remains found in the vehicles.

Alvie Porter's great grandson posted this comment:My great Grandpa, Alvie Porter, went missing back in 1969, he was 69-years-old. I remember my Grandpa putting up signs, asking people in town if anyone had seen his dad. Today, nearly 60 years later the car he was last seen driving was recovered from Foss Lake in SW Oklahoma along with two other people he was last seen with and another car containing three kids who went missing in a different car in 1970. I swam in the spot as a kid, as a teenager and just recently took my kids to feed the ducks near place where he was recovered.
